Still, if you need a card just for clearing the field, Cherry Bomb is usually a better choice, as while they are more expensive by 1 sun, they can do double the damage (and even more damage when used with the berry synergy cards), and won't leave an environment that damages your plants over time. Alongside, if you only want the environment itself, Hot Lava is playable for only 1 sun.

Against

This card is mostly used as a weaker field-clearer compared to Cherry Bomb. Hence, you do not need to worry about this card too much as long as you keep your zombies healthy. In fact, Camel Crossing can completely nullify Lava Guava's main ability, although only if you played it the turn before Lava Guava is played. However, you do want to know that this can also override one of your environments, so try not to always rely on one zombie environment. Just like the Cherry Bomb strategy, you can try to keep your zombies apart and not adjacent if you can. Or, since they only do 2 damage, you can play Knight of the Living Dead as he will not be affected.
